Government policies aimed at reducing greenhouse gas emissions from consumers need to be fairer for household income levels, says a University of Alberta researcher.

A U of A study published recently online in the journal Environment and Behaviour looks at the different sources of greenhouse gas emissions from consumers, based on their income levels. The wealthiest households in Alberta emit the most greenhouse gases, but too often, income disparity hasn't been factored in to current polices—such as the carbon flat tax that is levied to British Columbia residents.

Such policies tend to be based on data of CO² emitted by the average household—12.2 tonnes in Alberta according to the study, which surveyed 1,203 Albertans. Households in the province with the highest income actually emit 17.9 tonnes per year, while those with the lowest incomes generate 8.2 tonnes per year.

"Income disparity needs to be factored in when developing public policy, to avoid placing a disproportionate financial burden on people who can least afford it and who have contributed the least to the problem of greenhouse gases," said Emily Huddart-Kennedy, lead author and an assistant professor in the U of A Department of Resource Economics and Environmental Sociology.

People should continue to follow environmentally-friendly practices in their daily lives, but they can also have far-reaching environmental impact by buying smaller homes, taking public transit and most importantly, petitioning their government representatives "for environmental policies that are equitable," Huddart-Kennedy added.

Governments can consider providing incentives to build smaller homes, programs to reduce air travel and higher taxes for large or multiple vehicles, she added.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
